High Pressure Filter Pi 422/Pi 4220 Nominal pressure 400 bar/NG 150, 300, 450/NG 160, 250, 400 according to DIN 24 550
1. Features Efficient filter for modern hydraulik systems ■ Modular design ■ Compact design ■ Almost zero pressure loss due to flow-optimized design of components ■ Optical/electrical/ electronic contamination indicator
Quality filters, easy to service ■ Equipped with highly efficient Smx-filter elements ■ β-valued elements per ISO 4572 ■ High differential pressure stability and dirt holding capacity of the cartridges for optimum operating lifetime Worldwide distribution
2. Specifications Design:
Operating pressure: Test pressure: Temperature range:
Bypass opening pressure: Filter head material: Filter bowl material: Seal material: Switch point of optical/ electrical differential gauge:
inline filter, entry on side, exit on side, optionally on top 400 bar 520 bar -10 °C to +120 °C (other temperatures on request) ∆ p 7 bar GGG St NBR 0 0 ∆ p 5 bar
Electrical data of contamination indicator: Maximum voltage: Maximum switching current: Maximum switching capacity: Short-time switch-on capacity: Type of protection:
230 V~/= 2.5 A 60 VA / 40 W 70 VA IP 65 when inserted and secured normally open/normally closed PG 11 Ø 6-10
Contact: Cable connection: The switching function can be inverted by connecting the electrical part the other way round (normally closed or normally open contact if the differential pressure increases). Owing to the switch-on capacity of the 70 VA, the indicator is also suitable for controlling small contactors or contactor relays. Examine the possibility of quenching elements if there is inductance in the DC circuits. _ For more information and a detailed description, refer to our contamination indicator brochure! The standard version can be used for mineral oil-based liquids. Please ask for advice prior to using other media.
